One cannot have NULL values as input for Solr date fields. The multivalued part is irrelevant here. As it seems like you are getting the input data from a database, you will need to supply some invalid date for NULL date values. E.g., with mysql, we have: COALESCE( CreationDate, STR_TO_DATE( '1970,1,1', '%Y,%m,%d' ) ) The required syntax will be different for other databases. Regards, Gora
